MAX MPH CAFE RACER TIME TO MAKE THOSE UPDATES
« on: October 15, 2010, 02:45:24 AM »
Hi everyone its been a bit to long since i updated the build blog for my MAX MPH CAFE RACER, family - kids - business - work all seemed to get in the way.

But here goes, after the Thundersprint outing i ran the bike on the road through the summer, the more i used it the more i noted things that needed sorting. Heres a quick list.


@ Front brakes need improving (bigger piston in master cylinder required)

@ Rear cable operated brake not efficient at all

@ Fibreglass fuel tank prone to leaks

@ Rear sets to wide & foul exhausts

1st Job the rearsets, ive dropped the pipes off & removed the spacers on the footpegs bringing them in by approx 25mm a side. All the extra linkages are removed & on the gearlever side its now very simple & clean with just 2 rose joints & a rod (the pic shows the mock up using stud iron I will fab a new rod this week) The angle of the lever is now spot on for my foot position when on the bike.




Next stop excuse the pun, the back brake, the cable operating system i built wouldnt work effectivley how ever many times i adjusted it, also the extention arm on the lever tended to try to twist the leaver instead on rotating it. I spotted on a few Classic Race Hondas that they had reversed the brake activation arm on the drum so it pointed up instead of down. Once i had done this i removed all the old rearset linkage and cut a Y shaped plate from alloy plate, once in position i bent the activation arm to line up with the rear brake arm.


Heres a shot of the mock up, i also bolted a stainless allen bolt through the rearset mount as a stop for the pedal return, ive tested this and it works very well with the minimum of pedal travel. Next i will clean up the brackets & fab a new brake rod arm.

Ive also decided to go for a 4 into one exhuast system exiting just under the foot peg, more on that next week.

Thats it for now as off to the Stafford Show for a few bits, next update I will cover the Alloy Tank & exhaust system

I really like the first picture. K81s, muey nostalgic.

On your brake set up, I can understand your frustration. You may have some with the hard rod set up as well.

Suggestion: pull your shocks and raise and lower the rear wheel through its range of motion. See if the brake doesn't actuate itself from the geometry of the linkage.

ASsuming you haven't already ridden it and proved it works OK.

Suspension is at pretty near full extension now on the stand. So as the wheel travels up, the linkage will push the brake arm on the hub backwards and possibly activate the brake. Maybe not, depends on how much cllearance you have with the shoes to the drum. That's the advantage of a cable brake, if you didn't already know.

Very clean fabrications.

I'm liking this CR style so much I might have to get a fairing like yours.

Would love more info on fitment etc.
